DETAILED DESCRIPTION OF THE FIGURES

Various embodiments of the presently disclosed apparatus will now be described in detail with reference to the drawings, wherein like reference numerals identify similar or identical elements.

In the drawings and in the description that follows, the term “ proximal,” will refer to the end of a device or system that is closest to the operator, while the term “distal” will refer to the end of the device or system that is farthest from the operator. Similarly, the terms ventral, dorsal, medial, and lateral shall have their accepted meanings in the anatomic and medical arts, here used to describe relative orientations on the device in question.

With reference to FIG. 1, an embodiment of a Media Dispenser 1000 is shown. Media dispenser 1000 includes a hopper 1100, a hopper cover 1115, a base 1200, and a chute 1300.

Referring now to FIGS. 2 and 3 together, hopper 1100 is a substantially rigid member having a v-shaped profile when viewed from the front as shown in FIG. 2. Hopper 1100 is substantially enclosed, save for the dorsal end thereof, thereby defining a mouth 1110. There is a valve 1120 disposed upon the ventral-end portion of hopper 1100. Valve 1120 is an implementation of a butterfly valve including a cylindrical port 1122, a disc 1123, and an actuating lever 1125. Disc 1123 is mechanically coupled to lever 1125 such that radial translation of lever 1125 about valve 1120 rotates disc 1123 thereby obscuring or opening there channel therebehind.

According to further embodiments of the present disclosure not shown in the figures, the valve at the ventral-end portion of the hopper may be a ball valve, a choke valve, a diaphragm valve, a gate valve, or a globe valve. Valves of the preceding general types are disclosed at least in U.S. Pat. Nos. 3,635,439, 3,565,104, 3,631,882, and 3,559,949 respectively which are incorporated by reference herein in their entirety.

Further still, there are other embodiments of the present disclosure where there are no structures within the outlet tube and the functionality of a valve is accomplished by the media itself. In such a configuration, the outlet of the device is placed into an empty container and media is allowed to exit. Once the media rises to a sufficient level to block the outlet, flow of the media is interupted.

The dorsal-end portion of lever 1125 is slideably coupled to an actuate channel 1130 disposed upon the dorsal-end portion of hopper 1100.

Referring now to FIG. 3, hopper 1110 is comprised of an anterior plate 1131, a medial body 1132, and a posterior plate 1133. Anterior plate 1131, medial body 1132, and posterior plate 1133 may be joined by a number of processes including for instance bolts, snap fits, press fitting, adhesives, co-molding, or a combination thereof. The ventral-end portion of medial body 1132 is inclined so as to move material toward valve 1120.

Returning now to FIG. 1, base 1200 is a substantially rigid, hollow member having a substantially triangular profile when viewed from the front. There are a pair of wheels 1210 rotably coupled to one lateral ventral-end portion of base 1200.

Referring now to FIG. 5, there is a bag dispenser 1400 disposed within the lateral dorsal-end portion of base 1200 having a narrow longitudinal slit 1410 with an enlarged aperture 1420 disposed at the center thereof. There is a volume disposed medially from slit 1410 within which bags may be stored.

Referring now to FIGS. 7, 8, and 9 together, a media dispenser 2000 is shown having radially geared lever coupled to a chute in substantially orthogonal relation to the travel plane of the lever. The chute is open at the dorsal end thereof to the hopper above and has a closed and open shape disposed upon the ventral end thereof. Upon radial translation of lever, the chute rotates within a channel that in turn has an open and closed portion. Said configuration is such that when the two open portions are aligned, the ventral portion of the chute is in communication with the volume of the hopper above, thereby allowing media to exit the dispenser via gravity.

A method of using the subject of the present disclosure will now be described. A media dispenser 1000 is provided in a first, empty state, as shown in FIG. 1. A user may fill the media dispenser by translating cover 1115 dorsally with respect to the remainder of the assembly, thereby separating cover 1115 from media dispenser 1000 and revealing the internal chamber of hopper 1110. Next, a user may fill hopper 1110 with granular media, including for instance cat litter, dog food, rice, salt, or dried beans. Once the hopper is filled to the desired level, cover 1115 is replaced thereupon with a slight application of ventral pressure.

Next, a cavity, including for instance a bowl or litter box is placed under chute 1300. A user may open valve 1120 by grasping lever 1125 and translating it radially relative to the rest of the assembly. The linkage between lever 1125 and flap 1123 rotates flap 1123 thereby opening the butterfly valve and allowing media to exit valve 1120 into chute 1300 and subsequently the cavity. When sufficient media has been moved into the cavity, lever 1125 may be translated back to its initial state, thereby closing valve 1120.
